Determining it with a target hook doesn't make sense. What's more appropriate would be determining both rounded-up and rounded-down strings to get bounds on the possible length.
Yes, that's a better solution, thanks. Is there anything else, particularly in the floating point area, that you think should be changed or improved? Martin
